Objective: To observe the changes in ceal tissue after explosive ceal injury and the effect of seawater soaking on the healing of cea after explosive injury with the help ofoptical microscope. Methods: Make 10 similar explosive injury models of rabbit′s eyeball using 10 adult greyrabbits. For each rabbit, both eyes are artificially injured through explosion; its right eye is the comparison eye and after the injury the left eye is soaked in seawater for 30 minutes.Conduct slit lamp examinations, fluorescein dyeing, and ultrasonic cea thickness metering on the ceas at intervals, that is, before the injury, 1 , 2, 3, 4, 5, 7, 9, 12, 15days after the injury respectively. Examine the ceas under the optical microscope andmake comparisons.Results: The ceal thickness of the experiment eye becomes apparently thicker than thatof the comparison eye after the injury. The ceal clouding of the former apparentlyaggravates compared with the latter. The healing of ceal epithelium in the injured eye isslower compared with that in the comparison eye. Comparative examination under the opticalmicroscope shows: after the injury, the ceal tissue of the experiment eye changesdistinctly, its healing is delayed and the vascularization degree becomes high in cealstroma.Conclusion: Scars and vascularization of various degrees will appear in ceal stroma afterexplosive injuries. Seawater soaking will have bad effects on the healing of the ceainjured in explosions.
